WEIGHING-MACHINE.

SPECIFICATION formng part of Letters Patent No. 616,857, dated December2'7, 1898.

Application filed February 8,1898. Serial No. 669,*548. (No model.)

To rr/ZZ whom, it may conccrn:

Be it known that I, FRANOIS H. RICHARDS, a citizen of the United States,residing at Hartford, in the eounty of I-Iartford and State ofConnecticut, have invented certain new and useful Improvements inlVeighiug-llaehines, of which the following is a specification.

This invention relates to weighingmachines, the object being to providean improved machine of this character adapted more especially to bemounted on a counter and automatically to weigh and deliver into bags orother receptacles comparatively small charges of material, and itincludes improved means for controlling the stream, said means involvinga pair of stream-controllers, and means for advancing` saidstream-eontrollers simultaneously a predetermined distance and forretracting one and sirnnltaneously ad- Vancinp; the other by reason ofwhich the mass sustained by the stream-eontrollers is loosened up topermit that stream-controller which steps the flow of material to theloadreceiver to be advanced without undue resistance thei-eto.

My improved machine also includes,in combination with strean-supplyingmeans, a pair of concentrically-reciprocatory stream -controllers, arocker provided with projecting` arms, and links connecting the armswith the respective stream-controllers,and the streamsupplying means mayconsist of a hopper having a series of stream-controllers at least twoof which are operated in such a manner that they advance simultaneouslyto a certain point, during which period only one of thestream-controllers acts on the supply-stream and beyond which period theother streamcontroller is advanced relatively to its companion to arrestthe supply.

The strean-eontrollers consist, preferably, of pan-valves, and I haveillnstrated three of them, two of said valves serving to reduce theVolume of the supply issuing from the hopper or similar device, whilethe third or supplemental valve outs off the reduced or drip stream, andthe nounting and operation of the several valves are such that theauxiliary valve does not come into contact with the material until theclose of the drip period, or when the load is completed, so that a veryslight resistance is offered to the rapid closure of said valve, and theeffective stroke is consequently an exeeedingly short one.

Another feature of the invention resides in means for actuating thestream-controller by power derivecl fron the closer, and to accomplishthis result I provide,preferably,a powertransmitter and connect the samewith the stream-controller and with the closer, said power-transmittercoperatin g with the weighing mechanisn and terminating, preferably, inafoot having` two faces disposed at angles to each other. This foot isadapted to coact with the beam and with a projection at the poising endthereof, the idle face of said foot resting upon said projection duringthe flow of the supply-stream into the load-receiver, so that when thebean or poising end thereof falls it serves the usual purpose ofcontrolling the action of the valve mechanism. On the opening of thecloser to discharge a load the foot is shifted out of operative relationwith the scale-beam, so that said beain can return to its primaryposition while the closer is open without Operating a valve; but whenthe closer begins to shut the angular face or foot-piece is caused toride upon the beam, which at this timeis stationary, thereby forcing thepower-transmitter Upward to result in retracting the stream-controllersor valves. Another feature of the invention consists of an improved beammechanism including` a main beam and an auxiliary beam fixed to saidmain beam at one side and extending beyond the axis of said main beanand graduated, commencing at O, near the end of said auxiliary beamfarthest from the axis of the main beam, and a weight mounted to moveupon the auXiliary beam and employed when weighing out leads ofdifferent sizes; and I prefer to enploy a second anxiliary beam having,`thereon a movable weight, the purpose of which is to conpensate for abag, it being usual to Weigh the bag as a part of the charge. The mainbeain is counterweighted at one end, and the load-receiver is Suspendedat the other end thereof, said beam being fulcrumed bet ween .the twopoints; and I prefer to secure the auxiliary beams to the counterweight,and they extend for some distance beyond the axis of the main beam, theload-weight being movable between said aXis and the extreme end of theauxiliary beam, which is gradu- ICQ ated between its free end to theaxis of the main beam.

In the drawings accompanying and forming part of this specification,Figure l is a front elevation of ny improved weighing-machine. Figs. 2,3, and l are side elevations of the machine as seen from the right inFig. l and show the positions occupied by the different parts during themaking and diseharging of a load. Fig. 5 is a longitudinal centralsection of the same. Figs. 6 and T are central views of the valvemeehanism in its two final positions. Fig. S is a longitudinal centralsection of a valve-actuator. Fig. 9 is a transversc section taken in theline cc tr, Fig. 8, and looking in the direction of the arrow; and Fig.10 is a sectional plan view taken in the line y y, Fig. 5.

Similar characters designate like parts in all the figures of thedrawings.

The framework for supporting the different parts of the machine consistsof the chambered base z?, in which the diseharge-hoppe' ll' is located,the side frames or uprights 3 and r, mounted on the base, and thebraekets 5 and G, resting on the uprights and eXtending oppositely fromthe supply-hopper ll, serving as a convenient means for supplying astream of material to the load-receiver of the weighing meehanism, andthe diseharge-hopper H' is adapted to receive the leads intermittentlydischarged from said load-reeeiver, and it is substantiallyfunnel-shaped, so that a bagmouth can be placed over the reduced endthereof, as shown in the several figures of the drawings.

The weighing mechanism involves a loadreceiver and a supportingscale-beam therefor and one or more auxiliary beams, preferably fixed tothe main beam, and the loadreeeiver and the main scale-beam arepreferably of the kind disclosed in Letters Patent No. 55,840, grantedto me October 29, 1895, to which reference nay be had. The loadreceiveris designated by G, and the supporting-beam thereof by B, theload-reeeiver being mounted upon the poising end of said beam and thelatter being fulcrumed, as at 2', upon the base 9, and the two arms 7 ofthe beam being joined by the cylindrical weight lV, which extends beyondone of the arms, as represented in Fig. 1, and such extended portioncarries a pair of auxiliary beams,hereinafter referred to.

The load-discharging means includes as a part thereof a closer, as L,adapted to cover the usual discharge-ontlet in the load-receiver, andmeans including a latch for holding` the closer shut. The closer isfixed to a rock-shaft 10, supported in bearings, as 12 and 12', securednear the lower edge of the loadreceiver, and it is shut bycounterweights, as 13 and 13', extending rearward therefrom.

The latch for holding the closer shut is designated by L and it is ofthe ordinary construction, it being adapted to engage the arm lof therocker R, fixed at its middle to a roch-shaft 15 on the load-reeeiver,the opposite arm 10 of said rocker being connected by the longitudinalrod 17 with the closer L, and said shaft is provided at its opposite endwith a crank-arm 18, connected by a rod li! with the closer L, the rods17 and 19 noving in parallelism as the closer opens and shuts.

The supply-hopper ll is located over and in position to supply a streamof material to the load-reeeiver G, the supply being controlled,preferably, by a series of pan-valves, two of which cope *ate during apredetermined period to reduee the volume of the supply-stream to adrip, which fiows into the nearly-loaded bucket to complete or top offthe load, after which the third or auxiliary valve is operated to cutoff the red uced or drip stream.

The two reducing-valves are preferabl y oppositely reeiprocative, andduring the rcducing period they move toward each other to reduce thesize of the supply-stream, while the auxiliary valve closes under thespace between the discharge edges of the two main valves to cut oil' thedrip-stream on. the completion of the load.

The main valves are desi gn aiied by V and Y', and the auxiliary valveby Y", and although I have shown two main or reducing valves it isobvious that one of them might be dispensed with. In the present casethe valves V and Y are coneentrically reciprocative, they moving forwardsimultaneously for a predetermined distance, beyond which point theauxiliary valve has an advancing movement for cutting off thedrip-stream,while the main valve V is slightly retracted, therebytending to loosen up the supplyand rednee as far as possible theresistanee to the final closure of the auxilia'y valve, which during thefirst period of operation of the valve mechanism does not come incontact with the supply-stream. Therefore it will be evident that myinvention involves as a feature thereof a stream-controlling meansincluding a pair of steam-controllers and means for advancing saidstream-controllers simultaneously a predetermined distance and forsubsequently retraeting one and advaneing the other simultaneouslybeyond this point.

Each of the valves Y, Y", and V includes a cut-Ott portion or valveproper consisting of blades 90, 21, and 22, and the valves Y and V" aresupported for oscillation upon the pivots or studs 23 and l-l, (see Fig.1,) extending oppositely from the supply-hopper, while the valve V' isSuspended from a similar pair of studs 25 and 26.

The several valves are operated by power applied to the rock-shalt 30,journaled in brackets 30' and 30, extending rearward from the uprights 3and ut, respectively, and provided with the rock-arms 31 and 32, and towhich are pivoted the links 33 and ill, liliewise attached at theiropposite ends to the valves V and Y", respeetively, and the tworock-arms are disposed substantiall y at right IOO IIO

angles to each other and form, in eftect, with the two links, togglesfor Operating, when the shaft is actnated, the three stream-controllersor Valves.

The valve V' is furnished with a crank-arm 35, connected with the valveV by the link 30, by reason of which when the valve V is operated by theshaft the valve V' will be moved toward or 'from the companionreducing-Valve.

In Fig. 2 the parts are represented occupying their primary positions,the full Volume of the supply being shown as enter-ing the emptyload-receiver and the several valves being wide open. lVhen theload-receiver has received a certain quan tity of material, it willdescend, thereby permittin g the three valves, which are gravity-valves,to shut for a short distance and until an actuator becomes effective toinpart a further and accelerated movement thereto, and the positions ofthe two rock-arms 31 and 32 and the connecting-links and 37& are suchthat on the initial motion of the shaft 30 the valves V and V" will bemoved sinultaneously under the outlet of the hopper H, while the valveV' moves from the opposite direction under said spout and toward thefirst-nentioned two valves; but it will be seen that the cut-oil blade22 is under the cut-oli' blade 20, whereby the first-mentioned part doesnot come in contact with the supply-stream. At the commencement of thepoising period or when the load has been nearly completed the finalmovement of the several valves will be interrupted by a suitable devicefor a sul'fieient length of time to permit the reduced or drip stream toenter the load-receiver through the space between the discharge edges ofthe valves V and V'. hen the load is completed, the valve mechanism isreleased, at which point an actuator becomes effective for rocking theshaft 30, so that the valve V" is advanced by thrusting the link 34: tothe left, and at the same time the pivotal point between the rock-arm 31and the lever 33 is slightly elevated, and the link 33 is drawn for ashort distance to the right, whereby the Valve V is moved in a'corresponding direction or retracted, which results in loosening up thematerial sustained thereby, so that during the final movement of thevalve V" the resistance to the rapid closure thereof is redueed verymateriall y and the retraction of the valve Y necessarily follows atthis time.

As hereinbefore stated, the several valves or ear 42, apertured toreceive the shaft 30 and held in place by the set-screw 43, passingthrough the same and engaging the shaft. The extreme rear end of thecasing is closed, while the opposite or forward end thereof is furnishedwith a removable cap or plug H, preferably in threaded engagementtherewith, by reason of which the ball or rollweight 41 may be insertedor removed from the casing, and when the cap or plug 44 is in place dustor dirt is positively excluded from the inside of said casing, so thatfree movement of the ball is assured.

The ball ll is of slightly less diameter than the interior of thecylindrical casing-LO, so that it can roll freely from end to endthereof, and to guide said ball in a straight path I preferably mount itupon a track consisting of the rails and 51, disposed in parallelism onthe floor or bottom of the casing and upturned at its outer end, as at52, so that when the lower end of the casing falls, as shown in Fig. a,the result will be gradually to arrest the movement of the rollingweight and to protect the same from in j ury, and said weight preferablyabuts against buffers, as 53 and 54, Secured to the opposite ends of thecasing and constructed, preferably,ot` leather or other similarmaterial, the buffers being in the form of.

disks held against the plug and the closed end of the casing,respectively, and riveted in place, as at 53' and 54:'.

In Fig. 2 the several valv'es are shown wide open and the rolling weightetl is represented against the inner end or removable plug 44 of thecasing. When a certain proportion of the load has enteredtheload-receiver, it descends, as before stated, and as it does so thevalves V, V, and V" are permitted to advance by their own weight totheir secondary positions, (represented in Fig. 3,) or until a deviceoperative with the ValVes strikes a stop upon the weighing mechanism,which stop arrests the further progress of the valves until the load iscompleted, and it will be observed on inspection of said Fig. 3 that thefloor of the casing is disposed slightly below a horizontal line,comnencing at the inner end thereof, so that when the horizontal line iscrossed by the floor of the casing the ball 41 can drop to the right orfrom end to end of the casing, whereby when the Valve mechanism isreleased the shaft 30 will be rocled by the weighted end of the casing40 to operate the valve mechanism in the manner aforesaid.

The means for arresting the operation of the valve consists, preferably,of astop, as 60, of the by-pass type, mounted upon the load-receiver anddisposed in the path of the rod or bar 01, fixed to and depending fromthe rock-shaft 30. At the com nencement of the drip period the free endof the by-pass will be engaged by the rod 61, so as to block temgorarilythe movement of the three valves. On the completion of the load theby-pass 00 will pass 'off the rod (il, thereby releasing the g IOO IIO

4: &16,857

valvc-aetuator A, whereby the weighted end thereof can drop to impart tothe valves their final movements.

The operation of the several valves is controlled partly by the beam Band partly by the closer L in the following manner: The rock-shaft 30carries a crank-arn 63, te which the rod 6& is pivoted, said rodterninating in a foot 65, having angular faces 66 and 67, constitutingwhat might be termed the working face and the idle face, respectively,and during the normal operation of the machine the face 67 is held incontact with the projection or antifriction-roll 68 at the poising endof the beam B.

As before stated, the angular face 67 of the foot is held in engagementwith the antifriction-roll 68 by means preferably connected with thecloser for a purpose that will hereinafter appear. As the beam descendsfrom its highest to its lowest position (shown in Figs. 2 and 3,respectively) the antifrictionroll falls away from the angular face 67,and consequently permits the operation of the valve mechanism.

The means for eifecting the discharge of the load consists of a tripperT in the form of a pin on the reciprocatory rod 64, which strikes theend of the lever 70, pivoted to the loadreceiver, and which in turnlifts the weighted end of the closer-latchL', as shown in Fig. et, anddisengages said latch from the rockerR, thereby rcleasing the closer,which is then forced open by the weight of the mass in theload-receiver, the load then being discharged into the hopper and thenceinto the bag, as G', the mouth of which has been placed beneath thedelivery end of said hopper.

The closer L furnishes the power for operating the valve mechanism, thepower developed being transferred through the rod 6% to the severalvalves. On the opening of the closer the foot-piece 65 is shiftedthereby relative to the projection 68, so that the upper end of theworking or angular face 66 is carried opposite said projection, as shownin Fig. t, and the beam B can return to its normal position withoutOperating the 'od 6 \Vhen, however, the closer is shut, the angular face66 is drawn up 011 the antifriction-roll 68 by the closer, therebythrusting the rod il: upward, and consequently rocking the shaft in adirection reverse to the movements imparted thereto by the actuatorA,whereby the several valves controlling the supply-stream are opened.

The closer-supporting shaft 10 is provided with a rock-arm 75, to whichthe link 76 is pivoted, said lini; being likewise attached at itsopposite end to the rocking lever 7 7 pivoted, as at 78, to theload-receiver and connected at its opposite end to the lower extremityof the red 6& by the link hen the latch L' is tripped, the closer isforced open, and on this operation the link 7 6 is moved to the left,thereby oppositely throwing the link 79, and consequently moving theangular face 67 out of contact with the antifrietion -roll and shiftingthe footpiece 65 until the extreme inner end or highest point of theinclined working face 66 is opposite said roll. When the closer isopened, the mass is of course discharged, and the loadreceiver beinglightened the beam returns to its primary position; but it cannot, asbefore stated, apply any thrust to the rod 64. On the shuttin g of thecloser by the counterweight lS, this motion being a rapid one, theangular faces 66 and 67 are caused to ride upon the antifriction-roll 68by reason of the connections between the said closer and footpiece, sothat the rod 6-t is elevated to open the several valves and permit thesupply to enter the load-receiver.

To prevent the closer L being forced open by the infiowing stream, Iprefer to mount in the receiver the angular plate 88, Iianged at itsopposite ends, as at 86, said ilanges being secured by rivets or otherconvenient means to the opposite sides of the load-receiver, and thisplate is of such width as to receive the full Volume of the supply, asshown in Fig. 5, on the opening of the several valves, thereby toprevent the application of an undue pressure upon the closer during itsfinal shutting movement.

My improved machine is especially adapted for store use, where it can bemounted upon a counter for weighing out loads of material incomparatively small quantities, and I provide means whereby loads ofdifferent weights can be automatically weighed out and delivered intobags, &e

An auxiliary or load beam is represented at 80, it eonsisting of alongitudinal arm fitted at one end in a notch 8l in the extended portion82 of the beam-weight XV and held in the notch by a cap or flat plate 83and against the upper flat face 84: of the weight and maintained inplace by the set-screw 85, in threaded engagement with the beam-weight,said anxiliary beam being held against longitudinal movement by the pin86, disposed in a bore in the weight \V and fitting in a keyway in saidauxiliarybeam. The auxiliarybeam extends considerably beyond the axis ofthe main beam B and is graduated, commencing at O at the end farthestfrom said axis, the graduations indicating pounds and halfponnds, andsaid auxiliary beam carries for sliding movement a load-weight 87,adaptcd to be held in an adjusted position by the index 88, secured tosaid weight and fitting in notches on said auxiliary beam.

XVhen the index 88 of the load-weight 87 is in the notch correspondingwith 0, the load-receiver and the beam mechanism will be exactlybalanced.

The range of movement of the weight 87 is between the Zero-point at theright end of the beam and the aXis 2' of the main beam l.

hen the weight 87 is moved from the zeropoint toward the left, it addsto the efieiency of the beam-weight XV, and the variation is IOC IIC

indicated in pounds on the scalc of said auxiliary beam.

In the several figures of the drawings the weight 87 is upon the 10mark. hen the weight is moved to the right, the efficiency of the weightW is decreased.

It is cnstomaryin weighing out goods such as fleur, sugar, dac., toinclude the bag as part of the weight, and I have represented a devicefor compensating for the bag, which is not placed upon the weighingmechanism, the means consisting of an auxiliary beam 90, graduated atits right end and carrying the bag-weight 91, said auxiliary beam beingfitted in the notch 92 on the main weight W and being in parallelismwith the auxiliary beam SO and held in place by the means which securessaid beam 80. Said bag-weight is provided with an index 93, fitting innotches in line with the graduations of the auxiliary beam.

Should it be desired to weigh out a tenponnd package, the auxiliary orload weight 87 is moved along the beam 80 until the in des: SS fits inthe notch therein opposite the 10 77 mark, and the weight 91 is movedalong the beam until it is opposite the half-pound mark, therebysubtracting from the e'tliciency of the weight XV and consequentlyadding in effect a half-pound to the load-receiver, so that in realitythe load of material discharged is nine and one-half pounds.

For the purpose of facilitating the cleansing of the load-receiver Iprefer to nake the front and 'ear walls 95 and OG thereof removable,said walls being adapted to slide in gnideways, as 95', formed by thebent-over portions or ilanges OG' of the front and rear walls of theload-receiver and one portion of the right-angular plate 97, fixed inthe loadreceiver by a series of rivets, as 98.

The lower ends of the removable walls fit over the upper ends of theinclined portions 09 and 09' of the fixed portion of the loadreceiver,and by removing either one of said sliding walls 95 and 96 gives readyaccess to the interior of the load-receiver.

The operation of the hereinbefore-described machine, briefiy stated, isas follows: In Fig. 2 the parts are shown occupying their normalpositions, the angular face 67 of the rod (3& beingin contact with theantifriction-roll 68 of the main beam B and the valves V', V, and V"being wide open, while the closer L is held shnt by the latch L'engaging the rocker R.

When a predetermined portion of material has been received by theload-receiver, this descends, and the antifriction-roll 68, falling awayfrom the rod 64:, will permit the valves V, V', and V" to close bygravity, or until the rod (il, which is operatcd by the valves duringthe first period of their motion, strikes the by-pass GO, at which timethe botton of the casing 40 will have passed below a horizontal line,permitting the weight 41 to roll to the outer end of the casing, asshown in Fig. 3. \Vith the parte in the positions shown in said figurethe valves will be held so that a drip-stream can fiowbetween thedischarge edges of the valves V and V' and into the load-receiver tocomplete the load.

When the load is completed, the by-pass GO will pass off the rod 01,thereby releasing the actuator A, so that the weighted end thereof can-drop to impart an accelerated movement to the Valves V, V', and V" toswing the lastmentioned under the other two, the valves V and V' beingslightly retracted to loosen u p the supply. On the final movement ofthe valve the tripper T strikes the lever 70, which in turn disengagesthe latch L' from the rocker R, thereby releasing the closer L, which isforced open to discharge the load into the hopper H' and from thenceinto the bag G'. On the opening of the closer the rod 64 is shifted outof operative relation with the beam B by reason of its connections withsaid closer and the beam returns to its primary position. On theshutting of the closer the valve mechanism is opened in the mannerhereinbefore specified and the closer L is latched, when the operationis repeated.
